Help me buy my first bike

I'm buying my first bike, so I just wanted to hear about others' experiences.as this is my first bike i wanna start from small engine

I have three bikes in mind: Raider, Xtreme 125R, and N150 (if my budget allows). However, I'm leaning towards the Xtreme for its sportiness. As for TVS, based on my experience with the TVS Jupiter, the quality is better than Hero, but the service is worse. I can't decide.
